Guy insists on giving me a personal check [View all]

Had a carburetor listed locally and someone out of Texas bought it, wants me to cash his check wait 3 days
for it to clear and mail the carburetor to him. I smell a rat, he's quite adamant about sending only a check.

Doesn't the post office offer a cashier's check or money gram option at a fairly reasonable charge? He has said
he'll need to go to the Post Office to mail it.

Have one week left of cancer treatments, chemo side effects are kicking my butt.
